Revoke a grant request

If an authorized client no longer needs access to protected resources, the client can revoke the corresponding grant request.

These code snippets enable a client to revoke (cancel) a grant that it was previously issued. When a grant request is revoked, the request is placed into a finalized state and no further updates to the grant are allowed.

Before you begin

We recommend creating a wallet account on the test wallet. Creating an account allows you to test your client against the Open Payments APIs by using an ILP-enabled wallet funded with play money.

Revoke a grant request

TypeScript/JavaScript

Prerequisites

Initial configuration

If you’re using JavaScript, only do the first step.

1. Add "type": "module" to package.json.
2. Add the following to tsconfig.json

   {
     "compilerOptions": {
       "target": "ES2022",
       "module": "ES2022"
     }
   }

Import dependencies

import { createAuthenticatedClient } from "@interledger/open-payments";

Copied! Copy import { createAuthenticatedClient } from "@interledger/open-payments";

Initialize Open Payments client

const client = await createAuthenticatedClient({
  walletAddressUrl: WALLET_ADDRESS,
  privateKey: PRIVATE_KEY_PATH,
  keyId: KEY_ID,
});

Copied! Copy const client = await createAuthenticatedClient({ walletAddressUrl: WALLET_ADDRESS, privateKey: PRIVATE_KEY_PATH, keyId: KEY_ID, });

Revoke grant

await client.grant.cancel({
  accessToken: CONTINUE_ACCESS_TOKEN,
  url: CONTINUE_URI,
});

Copied! Copy await client.grant.cancel({ accessToken: CONTINUE_ACCESS_TOKEN, url: CONTINUE_URI, });

PHP

Prerequisites

Import dependencies

use OpenPayments\AuthClient;
use OpenPayments\Config\Config;

Copied! Copy use OpenPayments\AuthClient; use OpenPayments\Config\Config;

Initialize Open Payments client

$config = new Config($WALLET_ADDRESS, $PRIVATE_KEY, $KEY_ID);
$opClient = new AuthClient($config);

Copied! Copy $config = new Config($WALLET_ADDRESS, $PRIVATE_KEY, $KEY_ID); $opClient = new AuthClient($config);

Revoke grant

$response = $opClient->grant()->cancel([
  "access_token" => $ACCESS_TOKEN,
  "url" => $CONTINUE_URI,
]);

Copied! Copy $response = $opClient->grant()->cancel([ "access_token" => $ACCESS_TOKEN, "url" => $CONTINUE_URI, ]);
